When I was small Dave Vanian used to thrill and terrify me in equal measure: see Eloise the Damned
Oh definitely Dave Vanian
Plus
Wayne Hussey
Pete Burns (pre plastic surgery)
Nick Rhodes of Duran Duran
Carl McCoy (fields of the nephilim)
Robert Smith (but only with make-up on)
On the non gothy/makeup side:
Definitely Rik Mayall
Jay Rayner
James Martin
I also have a bit of a girl crush on Grace Dent and the girl from Aqua - oh and Patricia Morrison (Sisters of Mercy / The Damned)
